Description

Information sending method, information receiving method, repeater and network device Technical Field

The present application relates to the field of communication technology.

Background technique

Compared with traditional 3G (third generation mobile communication technology) and 4G (fourth generation mobile communication technology) systems, 5G (fifth generation mobile communication technology) systems can provide larger bandwidth and higher data rates, and can support more types of terminals and vertical services.

To this end, in addition to the traditional telecommunication spectrum, 5G systems are also deployed on new spectrum, which has significantly higher frequencies than the traditional telecommunication spectrum used by 3G and 4G systems. For example, 5G systems can be deployed in the millimeter wave band (28GHz, 38GHz, 60GHz and above, etc.).

According to the propagation law of wireless signals, the higher the frequency of the carrier, the more severe the signal fading will be during the propagation process. Therefore, in actual deployment, 5G systems need cell coverage enhancement methods more than previous 3G and 4G systems, especially 5G systems deployed in the millimeter wave frequency band. How to better enhance the cell coverage of 5G systems has become an urgent problem to be solved.

It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application.

Summary of the invention

In order to better solve the coverage problem of cellular mobile communication systems in actual deployment, it is a common deployment method to use RF relays (RF Relay/Repeater) to amplify and forward the communication signals between terminal devices and network devices. RF repeaters are widely used in the actual deployment of 3G systems and 4G systems. Generally speaking, an RF repeater is a device that amplifies and forwards the signals between devices in the RF domain. In other words, RF repeaters are a type of non-regenerative relay node that simply amplifies and forwards all received signals.

The inventors have found that one of the feasible solutions to the coverage problems encountered in the deployment of 5G systems is to use traditional RF repeaters to enhance coverage. However, since the forwarding behavior of traditional RF repeaters is not controlled by network devices, on the one hand, the effect of amplifying and forwarding the target signal may not be ideal. On the other hand, it may cause significant interference to other devices in the network, increase the noise and interference level of the system, and thus reduce network throughput. Specifically, taking the antenna direction as an example, compared with 2G, 3G and 4G systems, the 5G system adopts a more advanced and complex MIMO (multiple-input and multiple-output) technology. In the 5G system, especially for higher carrier frequencies, directional antennas become basic components of network devices and terminal devices, and sending and receiving signals based on beamforming technology is the basic signal transmission method in the 5G system. The (analog) beam direction, width, etc. of network devices and terminal devices may change dynamically (that is, beam switching) due to factors such as position changes. However, the antenna of a traditional RF repeater cannot dynamically adjust its direction and has a wide beam. The beam direction and beam width of its transceiver antenna cannot flexibly match the location of the base station and terminal device and the dynamic changes of the beam direction and width of the transceiver antenna. When such a RF repeater is configured in a 5G system, on the one hand, it may not have a significant performance/effect of amplifying/enhancing the target signal due to the mismatch between the beam direction and beam width of its transceiver antenna and the dynamic changes of the beam direction and width of the transceiver antenna of the network device and the terminal device. On the other hand, it may cause significant interference to other devices (e.g. network devices or terminal devices) within a larger range due to the use of a wider transmission beam, thereby increasing the noise and interference level of the entire system and reducing the network throughput. However, there is currently no method for the network device to control the forwarding behavior of the repeater.

In response to at least one of the above problems, an embodiment of the present application provides an information sending method, an information receiving method, a repeater and a network device.

According to one aspect of an embodiment of the present application, a network device is provided, including:

A sending unit receives downlink control information sent by a network device, wherein the downlink control information is in a first DCI format, and the downlink control information includes one or more first information fields for indicating a beam, and/or one or more second information fields for indicating time domain resources, and/or one or more third information fields for indicating a subcarrier spacing.

According to another aspect of an embodiment of the present application, a repeater is provided, including:

A receiving unit sends downlink control information to a repeater, wherein the downlink control information is in a first DCI format, and the downlink control information includes one or more first information fields for indicating a beam, and/or one or more second information fields for indicating time domain resources, and/or one or more third information fields for indicating a subcarrier spacing.

According to another aspect of an embodiment of the present application, a communication system is provided, comprising: the repeater of the aforementioned aspect and/or the network device of the aforementioned aspect.

One of the beneficial effects of the embodiments of the present application is that the beam of the repeater can be indicated through the DCI in the first DCI format, and the beam of the repeater can be controlled by the network device so that the beam of the repeater when forwarding (forwarding downlink/uplink signals) can match the beam of the terminal device that receives/sends the signal, thereby improving the effect of amplifying/enhancing the signal, while reducing interference to other devices in the network and improving network throughput.

In the embodiments of the present application, the term "network device" refers to, for example, a device in a communication system that connects a terminal device to a communication network and provides services for the terminal device. The network device may include, but is not limited to, the following devices: base station (BS), access point (AP), transmission reception point (TRP), broadcast transmitter, mobile management entity (MME), gateway, server, radio network controller (RNC), base station controller (BSC), etc.

Base stations may include but are not limited to: NodeB (NodeB or NB), evolved NodeB (eNodeB or eNB) and 5G base station (gNB), IAB host, etc., and may also include remote radio heads (RRH, Remote Radio Head), remote radio units (RRU, Remote Radio Unit), relays or low-power nodes (such as femto, pico, etc.). And the term "base station" may include some or all of their functions, and each base station may provide communication coverage for a specific geographical area. The term "cell" may refer to a base station and/or its coverage area, depending on the context in which the term is used.

In the embodiments of the present application, the term "user equipment" (UE) refers to, for example, a device that accesses a communication network through a network device and receives network services, and may also be referred to as "terminal equipment" (TE).

Traditional repeaters do not have the ability to communicate with network devices. Therefore, although traditional repeaters can help enhance signal strength, they are not flexible enough to cope with complex environmental changes. Deploying traditional repeaters in 5G networks (especially in high-frequency 5G networks) may cause unnecessary interference to other network devices and/or terminal devices, thereby reducing the transmission efficiency of the entire network (for example, throughput). In order to make the forwarding of repeaters more flexible to adapt to the characteristics of 5G networks, network devices need to assist repeaters and be able to configure the forwarding of repeaters according to network conditions.

In order to enhance the coverage of NR, 3GPP Rel-18 proposed the network-controlled repeater (NCR) solution to forward signals between network devices and terminal devices. NCR can communicate directly with network devices through control links to assist NCR's forwarding operations.

FIG1 is a schematic diagram of an NCR of an embodiment of the present application. As shown in FIG1 , NCR 102 is configured between a network device 101 and a terminal device 103. NCR 102 may include the following two modules/components: a mobile terminal (NCR-MT) of the repeater and a forwarding unit (NCR-Fwd) of the repeater; NCR-Fwd may also be referred to as a routing unit (NCR-RU) of the NCR. NCR-MT is used to communicate with the network device (interact information), and NCR-Fwd is used to forward signals between the network device and the terminal device. NCR-MT and NCR-Fwd are functional entities, and their functions may be implemented by the same or different hardware modules.

As shown in Figure 1, the NCR of the embodiment of the present application may have three links: a control link (control link, C-link), a backhaul link (or backhaul link, BH link) for forwarding, and an access link (access link, AC link, also known as NCR-UE link). Among them, C-link is used for communication between NCR and network equipment. BH link is used for the forwarder to receive a signal to be forwarded from the network equipment, or to forward a signal from the terminal equipment to the network equipment. AC link is used for the forwarder to forward a signal from the network equipment to the terminal equipment, or to receive a signal to be forwarded from the terminal equipment. Specifically, NCR-MT communicates with the network equipment through C-link; NCR-Fwd forwards signals through BH link and AC link.

In an embodiment of the present application, a repeater can communicate with a network device, and the repeater can receive a communication channel/signal sent by the network device, and demodulate/decode the channel/signal, thereby obtaining information sent by the network device to the repeater. The signal processing process is hereinafter referred to as "communication". The repeater can also forward a channel/signal transmitted between a network device and a terminal device. The repeater does not demodulate/decode the channel/signal, but can perform amplification and other processing. The signal processing process is hereinafter referred to as "forwarding". "Communication" and "forwarding" are collectively referred to as "transmission". In addition, "sending or receiving on an AC (or BH) link" can be equivalent to "forwarding on an AC (or BH) link", and "sending or receiving on a control link" can be equivalent to "communicating on a control link". The above terms are for convenience of explanation only and do not constitute a limitation on the present application. In some cases, "forwarding unit" can be interchangeable with "forwarding behavior".

In the embodiments of the present application, the repeater can also be expressed as a network controlled repeater (NCR), a repeater, a RF repeater, a repeater, a RF repeater; or it can also be expressed as a repeater node, a repeater node, a repeater node; or it can also be expressed as an intelligent repeater, an intelligent repeater, an intelligent repeater, an intelligent repeater node, an intelligent repeater node, an intelligent repeater node, etc., but the present application is not limited to this.

In the embodiments of the present application, the network device may be a device of the service cell of the terminal device, or a device of the cell where the repeater is located, or a device of the service cell of the repeater, or a parent node (Parent node) of the repeater. The present application does not impose any restriction on the name of the repeater. As long as the device can realize the above functions, it is included in the scope of the repeater of the present application.

In the embodiment of the present application, the high-level signaling may be, for example, radio resource control (RRC) signaling; RRC signaling may include, for example, an RRC message (RRC message), for example, a master information block (MIB), system information (system information), a dedicated RRC message; or an RRC information element (RRC information element, RRC IE); or an information field included in an RRC message or an RRC information element (or an information field included in an information field). The high-level signaling may also be, for example, a media access control layer (Medium Access Control, MAC) signaling; or a MAC control element (MAC control element, MAC CE). However, the present application is not limited thereto.

Various implementations of the embodiments of the present application are described below in conjunction with the accompanying drawings. These implementations are only exemplary and are not intended to limit the present application.

Embodiments of the first aspect

An embodiment of the present application provides a method for sending information, which is described from the perspective of a network device.

FIG. 2 is a schematic diagram of an information indication method according to an embodiment of the present application. As shown in FIG. 2 , the method includes:

201. The network device sends downlink control information to the forwarder, where the downlink control information is in a first DCI format, and the downlink control information includes one or more first information fields for indicating a beam, and/or one or more second information fields for indicating time domain resources, and/or one or more third information fields for indicating a subcarrier spacing.

It is worth noting that the above FIG2 is only a schematic illustration of the embodiment of the present application, but the present application is not limited thereto. For example, the execution order between the various operations can be appropriately adjusted, and other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description of the above FIG2.

In some embodiments, the downlink control information in the first DCI format is used to dynamically indicate/control an access link beam, or to control a forwarding unit of the forwarder, or to send side control information (side control information) or an access link beam indication.

In the embodiment of the present application, “downlink control information in the first DCI format” or “downlink control information using the first DCI format” or “DCI in the first DCI format” may also be directly referred to as “first DCI format”. The same is true for other DCI formats.

In some embodiments, the downlink control information in the first DCI format is not used for scheduling PDSCH or PUSCH.

In some embodiments, the downlink control information in the first DCI format may also be used to schedule PDSCH or PUSCH.

In some embodiments, the network device also sends downlink control information in a second DCI format to the repeater. The second DCI format is different from the first DCI format, for example, the DCI format numbers of the two are different (for example, the first DCI format is DCI format 2_8, and the second DCI format is DCI format 1_1). The second DCI format is used to schedule PDSCH or PUSCH and/or to activate or deactivate beam configuration, etc., and the embodiments of the present application are not limited to this.

In some embodiments, the DCI in the first DCI format and the DCI in the second DCI format are monitored in the same or different SSs, and/or use the same or different RNTIs (for example, to perform CRC scrambling).

In some embodiments, the first DCI format may be a newly introduced DCI format (e.g. DCI format 2_8, or 2_9, or 2_10, etc.), or it may be an existing DCI format (e.g. 1_1, or 2_0, etc.) (the existing DCI format currently also supports the functions in the embodiments of the present application), and the embodiments of the present application are not limited to this.

In some embodiments, the first DCI format is unicast or group common, and the DCI in the first DCI format includes one or more first information fields for indicating a beam, and/or, one or more second information fields for indicating time domain resources, and/or, one or more third information fields for indicating a subcarrier spacing. However, the present application is not limited thereto, for example, the DCI in the first DCI format may also include other information fields, such as one or more information fields for indicating whether the first information field indicates a beam, and for another example, one or more information fields for indicating on/off.

In some embodiments, the beam refers to a beam of an access link or a beam of a link between an NCR and a terminal device or a beam of an NCR used to receive signals from a terminal device and/or send signals to a terminal device. In other words, the beam refers to a physical beam of an access link that may be used by an NCR or a physical beam of an access link used for forwarding by an NCR.

The first information field is described below.

In some embodiments, a first information field is used to indicate a beam index, or at most one beam index, or multiple beam indexes. The beam index may include a beam index corresponding to a beam (or a (actual) physical beam) and/or a beam index not corresponding to a beam (or a (actual) physical beam).

In some embodiments, the beam index range is predefined and/or configured/indicated by high-level signaling. For example, all beam indexes within the beam index range are predefined or configured/indicated by high-level signaling, or a portion of the beam indexes are predefined and a portion of the beam indexes are configured/indicated by high-level signaling. For the latter, for example, the beam index of the corresponding beam is predefined, and the beam index of the non-corresponding beam is configured/indicated by high-level signaling, but is not limited thereto.

The beam index X does not correspond to an actual physical beam, and the beam indices {X+1, X+2, …, X+N _BI -1} correspond to actual physical beams, or the beam indices {X, X+1, …, X+N _BI -2} correspond to actual physical beams, and the beam index X+N _BI -1 does not correspond to an actual physical beam.

or

or

or

Or other values, which are not listed one by one here. In the above examples, the values of the beam index range are continuous, but the present application is not limited to this, and may also be discontinuous.

In some embodiments, the correspondence between the beam index and the beam can be predefined and/or configured by high-level signaling and/or OAM. In the case of configuration by OAM, the specific interactive information depends on the implementation. For example, the mobile terminal of the repeater (NCR-MT) can report beam/antenna related characteristics through OAM, and the network device can configure the beam and/or beam index of the NCR through OAM. The information exchanged between the NCR-MT and the network device through OAM is carried by the data radio bearer DRB, for example.

In some embodiments, NCR-MT can indicate/report the maximum number of DRBs it supports in the UE capability (UECapabilityInformation message). If it is not indicated/reported (or it does not exist in the UE capability), NCR-MT does not support DRB. Based on DRB, NCR-MT is connected to the OAM system through a protocol data unit PDU session or a packet data network PDN session (PDU session, the data of PDN session is carried by DRB). In other words, NCR-MT can establish a PDU session or PDN session for OAM, thereby exchanging OAM information through the PDU session or PDN session. For the PDU session or PDN session, NCR-MT can obtain the IP address or prefix (address/prefix) from the core network using the normal terminal device process.

In some embodiments, the beam index not corresponding to the beam is, for example, predefined and/or configured/indicated by higher layer signaling.

In some embodiments, when the beam index includes a beam index corresponding to a beam and a beam index not corresponding to a beam, the former is, for example, referred to as a valid beam index (first beam index), and the latter is, for example, referred to as an invalid beam index (second beam index). That is, if the first information field indicates a valid beam index, the first information field indicates the beam corresponding to the index, and if the first information field indicates an invalid beam index, the first information field does not indicate a beam. In some cases, the first information field must indicate a valid beam index, or the first information field may indicate a valid beam index or an invalid beam index.

In some embodiments, the bit value of the first information field includes a bit value with a corresponding beam index and/or a bit value without a corresponding beam index, including: all values of (the bits in) the first information field have a corresponding beam index; or, some values have a corresponding beam index and some do not. For the latter, the first information field must indicate the beam index (that is, the first information field must be set to a value with a corresponding beam index), or the first information field may indicate the beam index or may not indicate the beam index (that is, the first information field may be set to a value with a corresponding beam index (that is, indicating the beam index) or a value without a corresponding beam index (that is, not indicating the beam index)). Among them, "values without corresponding beam indexes" include: values that do not correspond to any physical beam (assuming that the beam index only includes beam indexes corresponding to actually existing physical beams), and/or reserved values (reserved value), and/or values used to provide other information (such as for indicating NCR-Fwd on/off, etc.) (assuming that the first information field is used to indicate both the beam and NCR-Fwd on/off), and/or predefined specific values (such as all "0"s, all "1"s, no examples are given here), which are used in certain specific situations, such as the protocol stipulates that in some cases, the first information field should be set to the specific value, or if the first information field is set to the specific value, it will affect how the NCR-MT processes/understands one or more other information bits or information fields in the DCI, but the present application is not limited to this. If the first information field does not indicate a beam index, the first information field does not indicate a beam. Combined with the above description about beam index, that is to say, "the first information field does not have/does not indicate a beam", includes: the first information field indicates an invalid beam index and/or the first information field does not have/does not indicate a beam index. "The first information field indicates a beam", includes: the first information field indicates a valid beam index and/or the first information field indicates a beam index.

In some embodiments, the first information field must indicate a beam, or the first information field may indicate a beam or may not indicate a beam.

The beam index includes a valid beam index {0} or is replaced by {1}. The bit value of a portion of the first information field, such as 1, is Reserved (reserved value) and has no corresponding beam index.

In the case of the first information field indicating the beam index or the valid beam index, it can also be said that the first information field indicates that NCR-Fwd is turned on. The first information field does not indicate the beam index or indicates an invalid beam index, which can also be said that the first information field indicates that NCR-Fwd is turned off.

The beam index includes valid beam indexes {0, 1, 2, 3} and invalid beam indexes {4, 5, 6, 7}, and all candidate bit values of the first information field have corresponding beam indexes.

Table 7 is an example of the first information field indicating the beam

波束索引包括有效的波束索引{0,1,2,3}或者可替换为{1,2,3,4}，所有第一信息域的候选比特值都有对应的波束索引。 As shown in Table 7,

The beam index includes a valid beam index {0, 1, 2, 3} or can be replaced by {1, 2, 3, 4}, and all candidate bit values of the first information field have corresponding beam indexes.

In some embodiments, the number of first information fields in the downlink control information of the first DCI format is predefined and/or configured or indicated by high-level signaling. In some embodiments, the number of first information fields or the maximum number of first information fields that can be configured (or can be included) in the first DCI format is related to the number of beams and/or the operating frequency band (or frequency range FR) and/or the bit width of the first information field, but is not limited thereto.

For example, the number of the first information fields is predefined, for example, the DCI of the predefined first DCI format includes N _1,fields first information fields, N _1,fields ≥ 1. For another example, the protocol stipulates that the number of first information fields is the same as the number of second information fields. If the number of second information fields is configured/indicated by high-level signaling, the number of first information fields can also be determined. For another example, the number of first information fields is related to the number of time domain resources that can be indicated by the second information field. For example, the number of first information fields is equal to the maximum number of time domain resources that can be indicated by the second information field. Among them, the maximum number is the maximum number of time domain resources that can be configured in the configuration in the time domain resource table corresponding to the second information field, which is 1, or the maximum number of time domain resources included, which is 2. For example, the maximum number of time domain resources that can be configured in the configuration in the time domain resource table is 4. According to the actual configuration, the time domain resource table includes 2 configurations, one of which includes 2 time domain resources, and the other configuration includes 1 time domain resource. That is, the maximum number of time domains included in the configuration in the time domain resource table is 2. If the above maximum number is the maximum number 1, the number of first information domains is 4; if the above maximum number is the maximum number 2, the number of first information domains is 2.

(Not limited to this, it can also be defined as a non-continuous set of integers greater than 0),

It is predefined and/or configured/indicated by high-level signaling, and indicates the maximum number of first information fields that can be configured (or included) in the DCI of the first DCI format.

For example, the number of first information fields in the downlink control information of the first DCI format is predefined and configured or indicated by high-level signaling. When the high-level signaling is not configured/indicated (for example, when the above-mentioned high-level parameter 1 is not provided), the number of first information fields in the first DCI format is predefined (that is, the protocol specifies a default number, and the default number is applied when the high-level signaling does not configure the number of first information fields). When the high-level signaling is configured/indicated (for example, when the above-mentioned high-level parameter 1 is provided), the number of first information fields in the first DCI format is configured/indicated by the high-level signaling.

In some embodiments, the bit width of the first information field is predefined and/or configured or indicated by high-level signaling. The bit width of the first information field is the number of bits included in the first information field. When the downlink control information includes multiple first information fields, the bit widths of different first information fields are the same or different, and the beam sets and/or beam index sets corresponding to different first information fields are the same or different. In some embodiments, the bit width of the first information field is related to the number of corresponding beam indexes and/or the number of valid beam indexes and/or the number of beams and/or the number of first information fields and/or the working frequency band (or frequency range FR), but is not limited thereto.

L _1,bitwidth may be defined to have the same or different values for different frequency domain ranges or working frequency bands. For example, for FR1, the value is 1 or 2, and for FR2, the value is 3 or 4. For different first information fields, the defined L _1,bitwidth values are the same or different. The protocol defines the bit width of the first information field as the number of beam indexes N _BI and/or the number of valid beam indexes N _BI,valid and/or the number of beams.

The definitions of each parameter are as described above and will not be repeated here.

and/or the number of beam indices N _BI and/or the number of valid beam indices N _BI,valid .

For example, the bit width is predefined and configured or indicated by high-level signaling. When the high-level signaling is not configured/indicated (for example, when the above-mentioned high-level parameter 2 is not provided), the bit width of the first information field is predefined (that is, the protocol specifies a default bit width, and the default bit width is applied when the high-level signaling does not configure the bit width of the first information field). When the high-level signaling is configured/indicated (for example, when the above-mentioned high-level parameter 2 is provided), the bit width of the first information field is configured/indicated by the high-level signaling.

The second information field is described below.

In some embodiments, one second information field is used to indicate one time domain resource index, or indicates at most one time domain resource index, or indicates multiple time domain resource indexes. The index may also be replaced by a sequence number.

In some embodiments, the second information field corresponds to a time domain resource table. The time domain resource table is predefined and/or configured by high-level signaling. The time domain resource table includes one or more time domain resource configurations. The time domain resource (TDRA) table (or simply referred to as the TDRA table) includes at least one row (column). Hereinafter, for the convenience of description, a row (column) is referred to as a TDRA configuration. A TDRA configuration includes one time domain resource or multiple time domain resources or does not include a time domain resource. A time domain resource is continuous or discontinuous.

In some embodiments, a time domain resource is defined, for example, by one or more of the following parameters: a time slot offset (used to determine the starting time slot), a symbol offset (used to determine the starting symbol in the time slot), a number of symbols (used to determine the length (duration) of the time domain resource), and a subcarrier spacing. These parameters are predefined and/or configured by high-level signaling. Among them, the time slot offset refers to the offset value between the time slot where the time domain resource is located or the first time slot where the time domain resource is located and the reference point. The value range of the offset value (for example, the minimum value and/or maximum value of the offset value) is predefined and/or configured by high-level signaling. The above-mentioned reference point is, for example, the time slot where the DCI of the first DCI format is located or the last time slot where the DCI of the first DCI format is located or the time slot where the previous time domain resource in the same configuration is located or the last time slot where the previous time domain resource in the same configuration is located. If a time domain resource configuration includes multiple time domain resources, the reference points of the time slot offsets of different time domain resources are the same (for example, they are all the time slots where the DCI of the first DCI format is located) or different (for example, for the first time domain resource: the time slot where the DCI of the first DCI format is located, and for the subsequent time domain resources, the time slot where the previous time domain resource is located). Symbol offset refers to the offset value between the first symbol of the time domain resource and the time slot in which it is located or the first symbol in the first time slot in which it is located. The symbol offset and/or the number of symbols must, for example, ensure that the configured time domain resources are in the same time slot, or the configured time domain resources can be in the same time slot or across time slots.

In some embodiments, the time domain resources in a configuration can be defined in the form of a list or sequence. For example, an IE is introduced, and the IE includes the parameters for defining a time domain resource. A configuration includes a list or sequence, and the list or sequence includes one or more fields corresponding to the above IE.

是一个配置所能包括的时域资源的最大数(例如N _TR＝4)和/或第一DCI格式的DCI中所能包括的第一信息域的最大数(例如

)。 In some embodiments, the number of time domain resources included in each configuration in the time domain resource table is the same or different. For example, the protocol stipulates that the number of time domain resources included in each configuration must be the same or can be different. When they must be the same, each T _list configuration must include N _TR time domain resources, where N _TR is the number of time domain resources included in a configuration (for example, N _TR = 1) and/or the number of first information fields included in the DCI of the first DCI format (for example, N _TR = N _{1, fields} = 4). When they can be different, a configuration may include

or

(Not limited to this, it can also be defined as a non-continuous set of integers greater than 0) time domain resources. Among them,

is the maximum number of time domain resources that can be included in a configuration (eg, N _TR =4) and/or the maximum number of first information fields that can be included in a DCI of a first DCI format (eg,

).

In some embodiments, a specific configuration in the time domain resource table does not include time domain resources. For example, the protocol specifies that the first configuration (index/sequence number is 0 or 1) in the time domain resource table does not include time domain resources. The specific configuration is predefined and/or configured/indicated by high-level signaling. If it is configured/indicated by high-level signaling, for example, the protocol specifies that the above-mentioned specific configuration (e.g., the first configuration) must be configured to not include time domain resources, or the above-mentioned specific configuration can be configured to include time domain resources or not include time domain resources.

In some embodiments, when a time domain resource configuration includes multiple time domain resources, different time domain resources do not overlap/overlap, or may overlap/overlap. Among the time domain resources listed in the configuration, the time domain resources listed later must be after the time domain resources listed earlier (the starting or ending position), or the time domain resources listed later may be before the time domain resources listed earlier (the starting or ending position). The embodiments of the present application are not limited to this.

In some embodiments, the second information field may indicate one time domain resource, multiple time domain resources, or no time domain resource by indicating a configuration in the time domain resource table.

In some embodiments, the time domain resource index may include a time domain resource index corresponding to the time domain resource and/or a time domain resource index not corresponding to the time domain resource. For example, the time domain resource index is an index or serial number of a column (row) configuration in the time domain resource table corresponding to the second information domain. If all configurations in the time domain resource table include time domain resources, the time domain resource index only includes the time domain resource index corresponding to the time domain resource; if there are configurations including time domain resources and configurations not including time domain resources in the time domain resource table, the time domain resource index includes the time domain resource index corresponding to the time domain resource and the time domain resource index not corresponding to the time domain resource. For another example, all configurations in the time domain resource list include time domain resources. If all values in the time domain resource index correspond to configurations in the time domain resource table, the time domain resource index only includes the time domain resource index corresponding to the time domain resource; if some values in the time domain resource index correspond to configurations in the time domain resource table, and some values do not correspond to any configuration in the time domain resource table, the time domain resource index includes the time domain resource index corresponding to the time domain resource and the time domain resource index not corresponding to the time domain resource. The time domain index not corresponding to the time domain resource is, for example, predefined and/or configured by high-layer signaling.

For example, the time domain resource index range is {I _start ,I _start +1,…,I _start +N _TI -1}, where I _start , for example, represents the starting time domain resource index or the minimum/lowest time domain resource index, and N _TI , for example, represents the number of time domain resource indexes, where I _start = 0 or I _start = 1 or I _start = -1 or I _start = -2 or other values, N _TI = 1 or N _TI = 2 or N _TI = 4 or N _TI = 8 or other values, which are not given one by one here. All N _TI time domain resource indexes correspond to a configuration/row/column in the time domain resource table, for example, assuming I configurations/rows/columns in the time domain resource table, N _TI = I. Alternatively, some of the N _TI time domain resource indexes correspond to the configurations in the time domain resource table, and the other part does not correspond to the configurations in the time domain resource table. For example, assuming that there are I configurations/rows/columns in the time domain resource table, N _TI =I+1, the time domain resource index I _start does not correspond to the configuration in the time domain resource table, and the time domain resource indexes {I _start +1, I _start +2,…, I _start +N _TI -1} respectively correspond to the configurations in the time domain resource table, or the time domain resource indexes {I _start , I _start +1,…, I _start +N _TI -2} respectively correspond to the configurations in the time domain resource table, and the beam index I _start +N _TI -1 does not correspond to the configuration in the time domain resource table. In the above examples, the values of the time domain resource index range are continuous, but this application is not limited to this, and it can also be discontinuous.

In some embodiments, when the time domain resource index includes a time domain resource index corresponding to a time domain resource and a time domain resource index not corresponding to a time domain resource, the former is, for example, referred to as a valid time domain resource index (first time domain resource index), and the latter is, for example, referred to as an invalid time domain resource index (second time domain resource index). If the second information field indicates a valid time domain resource index, the second information field indicates the time domain resource corresponding to the index, and if the second information field indicates an invalid time domain resource index, the second information field does not indicate a time domain resource. In some cases, the second information field must indicate a valid time domain resource index, or the second information field may indicate a valid time domain resource index or an invalid time domain resource index.

In some embodiments, the bit value of the second information field includes a bit value with a corresponding time domain resource index and/or a bit value without a corresponding time domain resource index. For example, all values of the second information field have a corresponding time domain resource index, or a part of the values have a corresponding time domain resource index, and a part of the values do not have a corresponding time domain resource index. For the latter, the second information field must indicate the time domain resource index (that is, the second information field must be set to a value with a corresponding time domain resource index), or the second information field may indicate the time domain resource index (set to a value with a corresponding time domain resource index) or not indicate the time domain resource index (set to a value without a corresponding time domain resource index).

For example, in the DCI of the first DCI format, the second information field may indicate a time domain resource index or may not indicate a time domain resource index (that is, the second information field may be set to a value with a corresponding time domain resource index (i.e., indicating a time domain resource index) or a value without a corresponding time domain resource index (i.e., not indicating a time domain resource index)). The "value without a corresponding time domain resource index" includes: a value that does not correspond to any time domain resource, and/or a reserved value (reserved value), and/or a value used to provide other information (e.g., for indicating NCR-Fwd on/off, etc.) (assuming that the second information field is used to indicate both time domain resources and NCR-Fwd on/off), and/or a predefined specific value (e.g., all "0"s, all "1"s, examples are not given here one by one), the specific value is used, for example, in certain specific situations, for example, the protocol stipulates that in some cases, the second information field should be set to the specific value, or if the second information field is set to the specific value, it will affect how the NCR-MT processes/understands one or more other information bits or information fields in the DCI, but the present application is not limited thereto. If the second information field does not indicate the time domain resource index, then the second information field does not indicate the time domain resource. In combination with the above description of the time domain resource index, "the second information field does not/does not indicate the time domain resource" includes: the second information field indicates an invalid time domain resource index and/or the second information field does not/does not indicate the time domain resource index. "The second information field indicates a beam" includes: the second information field indicates a valid time domain resource index and/or the second information field indicates a time domain resource index.

In some embodiments, the second information field must indicate the time domain resource, or the second information field may indicate the time domain resource or may not indicate the time domain resource.

The second information field is illustrated below using Tables 8 to 13 as examples.

Table 8 is an example of the second information field indicating the time domain resources

As shown in Table 8, the length of the time domain resource table is I=4, and the time domain resource index only includes valid time domain resource indexes {1, 2, 3, 4}. Some bit values 100, 101, 110, 111 are reserved values and have no corresponding time domain resource index.

Table 9 is an example of the second information field indicating the time domain resources

As shown in Table 9, the length of the time domain resource table is I=4, and the time domain resource index includes valid time domain resource indexes {0, 1, 2, 3} and invalid time domain resource indexes {-1}. Some bit values 100, 101, 110 are reserved values and have no corresponding time domain resource index.

Table 10 is an example of the second information field indicating the time domain resources

As shown in Table 10, the length of the time domain resource table is I=4, and the time domain resource index includes valid time domain resource indexes {0, 1, 2, 3} and invalid time domain resource indexes {-1}. Some bit values 111, 101, 110 are reserved values and have no corresponding time domain resource index.

Table 11 is an example of the second information field indicating the time domain resources

As shown in Table 11, the length of the time domain resource table is I=4, the time domain resource index includes a valid time domain resource index {1, 2, 3, 4} and an invalid time domain resource index {0} or the time domain resource index only includes a valid time domain resource index {1, 2, 3, 4}, '000' is a predefined specific value and has no corresponding time domain resource index. Another part of the bit values 111, 101, 110 are reserved values and have no corresponding time domain resource index.

Table 12 is an example of the second information field indicating the time domain resources

As shown in Table 12, the length of the time domain resource table is I=4, and the time domain resource index includes valid time domain resource indexes {0, 1, 2, 3} and invalid time domain resource index {0}.

Table 13 is an example of the second information field indicating the time domain resources

As shown in Table 13, the length of the time domain resource table is I=4, and the time domain resource index includes valid time domain resource indexes {0, 1, 2, 3} (or replaced by {1, 2, 3, 4}). All bit values have corresponding time domain resource indexes.

In some embodiments, the number of the second information fields is predefined and/or configured/indicated by high-layer signaling. The number of the second information fields may be related to the number of the first information fields and/or the number of time domain resources included in the configuration in the time domain resource table.

For example, when the number of second information fields is predefined, it can be predefined that the DCI of the first DCI format includes N _2,fields first information fields. For example, the first DCI format includes and only includes one second information field, that is, N _2,fields = 1. Or, the number of second information fields is the same as the number of first information fields, that is, N _2,fields = N _1,fields . Alternatively, the DCI in the first DCI format includes N _1,fields >1 or N _1,fields ≥1 first information fields, and the high-level signaling configures one of the above-mentioned time domain resource tables. When each configuration of the time domain resource table includes only 1 time domain resource or at most 1 time domain resource, the DCI in the first DCI format includes N _2,fields =N _1,fields second information fields (all corresponding to the time domain resource table). When one or more configurations or at least one configuration of the time domain resource table includes more than 1 time domain resource, the DCI in the first DCI format includes N _2,fields =1 second information field. The above is only an example and the present application is not limited to this.

For example, when the number of second information fields is configured/indicated by higher layer signaling, a new higher layer parameter 3 is introduced, and the higher layer parameter 3 is used to configure the number N _2,fields of second information fields in the first DCI format.

(不限于此，也可以定义为非连续的大于0的整数集)，

是预定义的，表示第一DCI format所能被配置的第二信息域的最大数。 For example,

(Not limited to this, it can also be defined as a non-continuous set of integers greater than 0),

It is predefined and indicates the maximum number of second information fields that can be configured in the first DCI format.

For another example, N _2,fields ∈{1,N _1,fields }, that is, the high-layer parameter may configure the first DCI format to include N _2,fields =1 second information field or N _2,fields =N _1,fields second information field.

For another example, the high-level parameter is used to configure the correspondence between the first information field and the second information field, and then indirectly/implicitly configure the number of the second information field. For example, if the configuration is one-to-one correspondence, it includes N _2,fields = N _1,fields second information fields, and if the configuration is many-to-one (or all-to-one), it includes N _2,fields = 1 second information field. In particular, if only one first information field is included, when configuring the number of second information fields (1), from the perspective of configuration, it can be "one-to-one correspondence" or "many-to-one".

On the other hand, when the number of the first information field and the second information field are both configured by high-level parameters, the number of the first information field and the second information field are respectively configured by different high-level parameters, or are configured by the same high-level parameter (that is, high-level parameter 1 and high-level parameter 3 are the same or different).

Different high-level parameters are configured separately

For example, a new high-level parameter is introduced to configure the number of the first information field N _1,fields , and another new high-level parameter is introduced to configure the number of the second information field N _2,fields . (See the previous descriptions respectively)

The same high-level parameter configuration:

For example, a new high-level parameter is introduced, and the high-level parameter is used to configure the number of the first information field and the second information field.

For example, the first information field and the second information field exist in pairs, and the high-level parameter is used to configure the number of {first information field, second information field} pairs. Alternatively, the high-level parameter is used to configure the number of blocks (blocks are introduced in "Listing Order"). Alternatively, the high-level parameter jointly configures the number of the first information field and the second information field, for example, configures {N _1,fields ,N _2,fields } pairs, for example, it can be configured {N,1}, or {N,N}, where N≥1, but is not limited thereto. Alternatively, the high-level parameter configures the number of the first information field and the second information field separately.

For another example, the high-level parameter is used to configure the number of first information fields N _1,fields or the number of second information fields N _2,fields , and the protocol stipulates that N _1,fields = N _2,fields , so that NCR-MT can also obtain the number of first information fields and second information fields based on the high-level parameter. That is to say, the high-level parameter is used to directly configure the number of first information fields and indirectly configure the number of second information fields, or vice versa, directly configure the number of second information fields and indirectly configure the number of first information fields.

For example, when the number of second information fields is predefined and configured/indicated by high-level signaling, when the high-level signaling is not configured/indicated (for example, when the above-mentioned high-level parameter 3 is not provided), the number of second information fields is predefined (that is, the protocol specifies a default number, and the default number is applied when the high-level signaling does not configure the number of second information fields), and when the high-level signaling is configured/indicated (for example, when the above-mentioned high-level parameter 3 is provided), the number of second information fields is configured/indicated by the high-level signaling.

In some embodiments, the bit width of the second information field is predefined and/or configured or indicated by high-level signaling. The bit width of the second information field is the number of bits included in the second information field. When the DCI in the first DCI format includes multiple second information fields, the time domain resource tables and/or time domain resource index sets corresponding to different second information fields are the same or different, and the bit widths of different second information fields are the same or different. The bit width of the second information field is related to the length I of the corresponding time domain resource table (that is, the number of configurations included) and/or the number of time domain resource indexes N _TI and/or the number of valid time domain resource indexes N _TI,valid .

其中Q为大于0的整数(例如Q＝1)，是预定义的和/或由高层信令配置/指示的。Q例如等于第二信息域中不用于指示时域资源索引的比特的数量(这里假设第二信息域中可以包括2部分候选比特值，其中一部分不用于指示时域资源索引)，或者不对应时域资源索引的(或者说不用于指示时域资源索引的)值的数量，或者，不对应有效的时域资源索引的值的数量，或者，无效的时域资源索引的数量，或者预定义的特定值的数量，或者上述两个或两个以上数量之和(例如无效的时域资源索引的数量+预定义的特定值的数量)。其中，预定义的特定值如前所述，此处不再重复。其中，若时域资源表(暗含长度I)和/或时域资源索引的数量N _TI和/或有效的时域资源索引的数量N _TI,valid是由高层信令(例如高层参数)配置/指示的，也可以说，该高层信令(例如高层参数)用于间接/隐式配置/指示第二信息域的位宽。 For example, the bit width of the second information field is L _{2, and the bitwidth} is determined by the length of the list.

Wherein Q is an integer greater than 0 (for example, Q=1), which is predefined and/or configured/indicated by high-level signaling. Q is, for example, equal to the number of bits in the second information field that are not used to indicate the time domain resource index (here, it is assumed that the second information field may include 2 parts of candidate bit values, one of which is not used to indicate the time domain resource index), or the number of values that do not correspond to the time domain resource index (or are not used to indicate the time domain resource index), or the number of values that do not correspond to the valid time domain resource index, or the number of invalid time domain resource indexes, or the number of predefined specific values, or the sum of two or more of the above numbers (for example, the number of invalid time domain resource indexes + the number of predefined specific values). Wherein, the predefined specific value is as described above and is not repeated here. Wherein, if the time domain resource table (implied length I) and/or the number of time domain resource indexes N _TI and/or the number of valid time domain resource indexes N _TI,valid are configured/indicated by high-level signaling (for example, high-level parameters), it can also be said that the high-level signaling (for example, high-level parameters) is used to indirectly/implicitly configure/indicate the bit width of the second information field.

For example, the bit width L _{2, bitwidth} of the second information field is configured or indicated by high-level signaling, for example, one or more new high-level parameters 4 are introduced, and the high-level parameter 4 is used to configure the bit width L _{2, bitwidth} of the second information field. For details, refer to the high-level parameter 2 to configure the bit width of the first information field, which will not be repeated here. For example, one of the above high-level parameters 4 is introduced, and the configured bit width is applied to all second information fields in the DCI of the first DCI format. Alternatively, multiple of the above high-level parameters 4 are introduced, which are respectively used to configure the bit widths of different second information fields.

For example, the bit width is predefined and configured or indicated by high-level signaling. When the high-level signaling is not configured/indicated (for example, when the above-mentioned high-level parameter 4 is not provided), the bit width of the second information field is predefined (that is, the protocol specifies a default bit width, and the default bit width is applied when the high-level signaling does not configure the bit width of the second information field). When the high-level signaling is configured/indicated (for example, when the above-mentioned high-level parameter 4 is provided), the bit width of the second information field is configured/indicated by the high-level signaling.

The following describes how the first information field and the second information field are arranged in the DCI of the first DCI format.

In some embodiments, the order of the information fields in the downlink control information includes: all the second information fields are arranged after or before all the first information fields, or the second information fields are arranged alternately with the first information fields.

In some embodiments, all N _2,fields second information fields precede or follow all N _1,fields first information fields.

For example: N _{1, fields} ≥ 1, N _{2, fields} = 1

Example 1: The second information field follows the first information field

First information field 1, first information field 2, ..., first information field N _{1, fields} , second information field

Example 2: The second information field comes before the first information field

Second information field, first information field 1, first information field 2, ..., first information field N _{1, fields}

For example: N _1,fields ≥ 1, N _2,fields = N _1,fields

Example 1: The second information field follows the first information field

First information field 1, first information field 2, ..., first information field N _{1, fields} , second information field 1, second information field 2, ..., second information field N _{2, fields}

Example 2: The second information field comes before the first information field

second information field 1, second information field 2, ..., second information field N _{2, fields} , first information field 1, first information field 2, ..., first information field N _{1, fields} .

In some embodiments, the second information field is arranged crosswise (interleaved) with the first information field. For example, the N _2,fields second information fields and the N _1,fields first information fields are cross-listed in the first DCI format in the order of the first information field first and the second information field second, or cross-listed in the order of the second information field first and the second information field second.

For example: N _{1, fields} ≥ 1, N _{2, fields} = 1

Example 1: first information field 1, second information field 1, first information field 2, ..., first information field N _{1, fields}

For example: N _1,fields ≥ 1, N _2,fields = N _1,fields

Example 1: first information field 1, second information field 1, first information field 2, second information field 2, ..., first information field N _{1, fields} , second information field N _{2, fields}

Example 2: second information field 1, first information field 1, second information field 2, first information field 2, ..., second information field N _{2, fields} , ..., first information field N _{1, fields} .

Example 3: The first DCI format includes N _blocks , in the order of block number 1, block number 2, ..., block number N _block . Each block defines one or more first information fields and one or more second information fields. In a block, the first information field and the second information field are arranged in the above manner. For example, each block includes a first information field and a second information field, N _block = N _{1, fields} = N _{2, fields} , and the first information field and the second information field in the same block correspond to:

Block 1: First information field 1, second information field 1 or second information field 1, first information field 1

Block 2: First information field 2, second information field 2 or second information field 2, first information field 2

…

Block N _block : first information field N _{1, fields} , second information field N _{2, fields} or second information field N _{2, fields} , first information field N _{1, fields} .

When the number _N1,fields of the first information fields and the number N2 _,fields of the second information fields are different, how to arrange the first information fields and the second information fields will not be illustrated one by one.

The following describes the correspondence between the first information field and the second information field and/or the correspondence between the beam (beam index) indicated by the first information field and the time domain resource indicated by the second information field.

In some embodiments, the first information field corresponds to the second information field one by one, or a plurality of the first information fields correspond to one second information field, or one first information field corresponds to a plurality of the second information fields.

(I) For _N1,fields ≥ 1, N2 _,fields = 1

In some embodiments, all first information fields correspond to one second information field, that is, all beams indicated by the first information fields are applied to one or more time domain resources indicated by the second information field (beams indicated by different first information fields are applied to the same or different time domain resources). The first information field (or the beam indicated by the first information field or the beam index or the effective beam index) and the time domain resources indicated by the second information field may correspond one-to-one or many-to-one or one-to-many. Among them, one-to-one correspondence, for example, means: a beam indicated by a first information domain corresponds to a time domain resource, and beams indicated by different first information domains correspond to different time domain resources indicated by a second information domain, or, one time domain resource corresponds to a beam indicated by a first information domain, and different time domain resources correspond to beams indicated by different first information domains; many-to-one, for example, means that beams indicated by multiple first information domains correspond to the same time domain resource, and beams indicated by different first information domains in multiple first information domains correspond to different frequency domain resources; one-to-many, for example, means that a beam indicated by a first information domain corresponds to multiple time domain resources indicated by a second information domain, and the multiple time domain resources may or may not overlap.

)，NCR-MT忽略第一信息域是指无需根据该第一信息域进行转发，例如：读取该第一信息域但无需根据该第一信息域转发，或者无需读取该第一信息域，进而无需根据该第一信息域转发)，即使第n+1或其后的第一信息域指示了波束或有效的波束索引或波束索引)和/或第n+1及其后的第一信息域必须指示无效的波束索引或不指示波束或不指示波束索引。 In some embodiments, in the DCI of the first DCI format, all first information fields must indicate a beam or a valid beam index or a beam index, or, there must be at least X (eg at least 1) first information fields indicating a beam or indicating a valid beam index or indicating a beam index (there may be one or more that do not indicate a beam or a valid beam index or do not indicate a beam index). In the latter case, for example, a portion of the first information fields (e.g., the first first information field) must indicate a beam or a valid beam index or a beam index, or any first information field may indicate or not indicate a beam or a valid beam index or a beam index, and/or, in the case where the nth first information field indicates an invalid beam index or does not indicate a beam or does not indicate a beam index, the nth first information field and/or the n+1th and subsequent first information fields are ignored by the NCR-MT (that is, the NCR-MT only considers that the first n-1 first information fields indicate a beam or a valid beam index or a beam index (described below)

), NCR-MT ignores the first information field means that there is no need to forward according to the first information field, for example: reading the first information field but not forwarding according to the first information field, or not reading the first information field, and then not forwarding according to the first information field), even if the first information field (n+1) or later indicates a beam or a valid beam index or a beam index) and/or the first information field (n+1) or later must indicate an invalid beam index or does not indicate a beam or does not indicate a beam index.

))，和/或，必须指示无效的波束索引或不指示波束或不指示波束索引或同样的波束或波束索引或者设置为同样的比特值(和第n个第一信息域相同)。特别地，该第n个第一信息域也可以称为无效的第一信息域。 In some embodiments, if the beam or beam index indicated by the nth first information field (except the first first information field) or the bit value set is the same as that of a previous first information field (for example, the adjacent previous (n-1) or the first first information field), the nth first information field and/or the first information field after the nth first information field (the n+1th and thereafter) is ignored by the NCR-MT (that is, the NCR-MT only considers that the first n-1 first information fields indicate beams or valid beam indices or beam indices (described below)

)), and/or, must indicate an invalid beam index or no beam or no beam index or the same beam or beam index or set to the same bit value (the same as the nth first information field). In particular, the nth first information field can also be called an invalid first information field.

In some embodiments, a first information field that does not indicate a beam or a valid beam index or a beam index and/or a first information field that is ignored by the NCR may be referred to as an invalid first information field, and a first information field that indicates a beam or a valid beam index or a beam index and/or a first information field that is not ignored by the NCR may be referred to as a valid first information field.

In some embodiments, since there is only one second information field, corresponding to the above “all first information fields must indicate beams or valid beam indices or beam indices”, the second information field must indicate N _1,fields time domain resources. That is, the configuration indicated by the second information field must include at least N _1,fields (eg must include N _1,fields ) time domain resources, that is, each configuration in the time domain resource table corresponding to the second information field (or the DCI of the first DCI format) must include at least N _1,fields (eg must include N _1,fields ) time domain resources. Corresponding to the above “at least X (eg at least 1) first information fields indicate beams or indicate valid beam indices or indicate beam indices”, the second information field must indicate at least 1 time domain resource. That is, the configuration indicated by the second information field must include at least X (eg at least 1) time domain resources, that is, each configuration in the time domain resource table corresponding to the second information field (or the DCI of the first DCI format) must include at least X (eg at least 1) time domain resources.

In some embodiments, the correspondence between the first information field (or the beam or beam index or valid beam index indicated by the first information field) and the time domain resources indicated by the second information field is determined according to the order in which the first information field is listed in the DCI of the first DCI format, and/or whether the first information field indicates a beam or indicates a valid beam index or indicates a beam index, and/or the order in which the time domain resources indicated by the second information field are listed in the time domain resource table configuration, and/or the order of the time domain resources indicated by the second information field in the time domain.

For example, the nth first information field (or the beam or beam index or valid beam index indicated by the nth first information field) corresponds to the nth time domain resource indicated by the second information field. For another example, the nth first information field indicating a beam or indicating a valid beam index or indicating a beam index (or the beam or beam index or valid beam index indicated by the nth first information field indicating a beam or indicating a valid beam index or indicating a beam index) corresponds to the nth time domain resource indicated by the second information field.

The first information field N (indicated beam index x_N, or indicated beam x_N) corresponds to the time domain resource y_N indicated by the second information field.

As shown in FIG3B , there are N first information Domains, according to the order listed in the DCI of the first DCI format, are the first information domain 1, the first information domain 2, ..., the first information domain N, only the first number N-1 first information domains indicate a valid beam index, the one second information domain indicates a first number N-1 time domain resources, the order of listing configured in the time domain resource table of the first number of time domain resources or the order of time domain resources in the time domain is y_1, y_2, y_3, ..., y_N-1, the first information domain 1 (indicated beam index x_1, or indicated beam x_1) corresponds to the time domain resource y_1 indicated by the second information domain, the first information domain 3 (indicated beam index x_3, or indicated beam x_3) corresponds to the time domain resource y_2 indicated by the second information domain, and so on, the first information domain N (indicated beam index x_N, or indicated beam x_N) corresponds to the time domain resource y_N-1 indicated by the second information domain.

Figure 3C is a schematic diagram of the corresponding relationship of an embodiment of the present application. As shown in Figure 3C, there are N first information fields in total, which are first information field 1, first information field 2,..., first information field N in the order listed in the DCI of the first DCI format. Only the first number of two first information fields (first information field 1 and second information field 2) indicate a valid beam index. The one second information field indicates a first number of two time domain resources. The order of listing of the two time domain resources configured in the time domain resource table or the order of the time domain resources in the time domain is y_1, y_2. The first information field 1 (indicated beam index x_1, or indicated beam x_1) corresponds to the time domain resource y_1 indicated by the second information field, and the first information field 2 (indicated beam index x_2, or indicated beam x_2) corresponds to the time domain resource y_2 indicated by the second information field.

FIG3D is a schematic diagram of the corresponding relationship in an embodiment of the present application. As shown in FIG3D , there are N first information fields in total, which are first information field 1, first information field 2, ..., first information field N in the order listed in the DCI of the first DCI format. Only a first number of two first information fields (first information field 1 and second information field 2) indicate a valid beam index, and the one second information field indicates time domain resources greater than the first number (e.g., N). The order of listing of the N time domain resources or the order of the time domain resources in the time domain configured in the time domain resource table is y_1, y_2, ..., y_N, the first information field 1 (indicated beam index x_1, or indicated beam x_1) corresponds to the time domain resource y_1 indicated by the second information field, the first information field 2 (indicated beam index x_2, or indicated beam x_2) corresponds to the time domain resource y_2 indicated by the second information field, the first information field 3 (indicates an invalid beam index) corresponds to the time domain resource y_3 indicated by the second information field, and so on, the first information field N (indicates an invalid beam index) corresponds to the time domain resource y_N indicated by the second information field. Since the first information field 3 does not indicate a beam, the NCR ignores the first information field 4 and the first information field thereafter, that is, the NCR ignores the time domain resources corresponding to the first information field that does not indicate a beam, and/or the first information field 4 and the first information field thereafter do not indicate a beam.

FIG3E is a schematic diagram of the corresponding relationship in an embodiment of the present application. As shown in FIG3E , there are N first information fields in total, which are first information field 1, first information field 2, ..., first information field N in the order listed in the DCI of the first DCI format. The first number N-1 first information fields indicate a valid beam index. In addition, the second information field 2 does not indicate a beam. The one second information field indicates more than the first number of time domain resources (for example, N). The order of listing of the N time domain resources in the time domain resource table configuration or the order of the time domain resources in the time domain is y_1, y_2. , ..., y_N, indicating the first number of beams, the first information fields correspond to the first number of time domain resources, the first information field 1 (indicated beam index x_1, or indicated beam x_1) corresponds to the time domain resource y_1 indicated by the second information field, the first information field 3 (indicated beam index x_3, or indicated beam x_3) corresponds to the time domain resource y_2 indicated by the second information field, and so on, the first information field N (indicated beam index x_N, or indicated beam x_N) corresponds to the time domain resource y_N-1 indicated by the second information field. NCR ignores the time domain resources that have no corresponding beams (or the remaining).

In the above examples, it is assumed that the number of time domain resources indicated by the second information field is the same as the number of the first information field, but the present application is not limited thereto and may be more or less than the number of the first information field.

In the above example, a beam indicated by a first information field corresponds to a time domain resource (i.e., the one-to-one correspondence mentioned above), and beams indicated by different first information fields correspond to different time domain resources indicated by a second information field, but the embodiments of the present application are not limited to this.

FIG3F is a schematic diagram of the corresponding relationship in an embodiment of the present application. As shown in FIG3F , beams indicated by multiple first information fields correspond to the same time domain resource (the aforementioned many-to-one situation), wherein there are N first information fields in total, which are first information field 1, first information field 2, ..., first information field N in the order listed in the DCI of the first DCI format, all indicating beam indexes, and the one second information field indicating N/2 time domain resources, and the N/2 time domains The order of enumeration configured in the resource time domain resource table or the order of time domain resources in the time domain is y_1, y_2,..., y_N/2, the first information domain 1 (indicated beam index x_1) corresponds to the time domain resource y_1 indicated by the second information domain, the first information domain 2 (indicated beam index x_2) corresponds to the time domain resource y_1 indicated by the second information domain, every two first information domains correspond to one time domain resource, and so on, the first information domain N-1 (indicated beam index x_N-1) and the first information domain N (indicated beam index x_N) correspond to the time domain resource y_N/2 indicated by the second information domain.

Figure 3G is a schematic diagram of the corresponding relationship of an embodiment of the present application. As shown in Figure 3G, a beam indicated by a first information field corresponds to multiple time domain resources indicated by a second information field (the aforementioned one-to-many situation), wherein there are N first information fields in total, which are first information field 1, first information field 2, ..., first information field N in the order listed in the DCI of the first DCI format, all indicating beam indexes. The one second information field indicates 2N time domain resources. The order of listing configured in the time domain resource table of the 2N time domain resources or the order of time domain resources in the time domain is y_1, y_2, ..., y_2N. The first information field 1 (indicated beam index x_1) corresponds to the time domain resources y_1 and y_2 indicated by the second information field. One first information field corresponds to two time domain resources, and so on. The first information field N (indicated beam index x_N) corresponds to the time domain resources y_2N-1 and y_2N indicated by the second information field.

(II) For N _1,fields ≥ 1, N _2,fields ＝N _1,fields

In some embodiments, the first information field (or the beam or beam index indicated by the first information field) and the second information field (or the time domain resource indicated by the second information field) are one-to-one corresponding or many-to-one corresponding or one-to-many corresponding. Among them, one-to-one corresponding means, for example, that a beam indicated by the first information field corresponds to a time domain resource indicated by the second information field, and beams indicated by different first information fields correspond to time domain resources indicated by different second information fields, or vice versa, a time domain resource indicated by the second information field corresponds to a beam indicated by the first information field, and time domain resources indicated by different second information fields correspond to beams indicated by different first information fields. Many-to-one means, for example, that beams indicated by multiple first information fields correspond to the same time domain resource indicated by the second information field, and beams indicated by different first information fields in the multiple first information fields are for different frequency domain resources and/or for different time domain resources indicated by the second information field. One-to-many means, for example, that a beam indicated by the first information field corresponds to time domain resources indicated by multiple second information fields, and the time domain resources indicated by the multiple second information fields may or may not overlap.

In the latter case, for example, a portion of the first information fields (e.g., the first first information field) must indicate a beam or a valid beam index or a beam index, or any first information field may indicate or not indicate a beam or a valid beam index or a beam index, and/or, if an invalid beam index or no beam or no beam index is indicated in the nth first information field, the nth first information field and/or the first information field (n+1) and thereafter are ignored by the NCR-MT (that is, the NCR-MT only considers that the first n-1 first information fields indicate a beam or a valid beam index or a beam index (described below)

In the latter case, for example, a part of the second information fields (e.g., the first second information field) must indicate a time domain resource or a valid time domain resource index or a time domain resource index, or any second information field may indicate or not indicate a time domain resource or a valid time domain resource index or a time domain resource index, and/or, if the mth second information field indicates an invalid time domain resource index or does not indicate a time domain resource or does not indicate a time domain resource index, then the mth second information field and/or the m+1th and subsequent second information fields are ignored by the NCR-MT (that is, the NCR-MT only considers that the first m-1 second information fields indicate a time domain resource or a valid time domain resource index or a time domain resource index (described below)

), NCR-MT ignores the second information field means that there is no need to forward according to the second information field, for example, the second information field is read but there is no need to forward according to the second information field, or there is no need to read the second information field, and then there is no need to forward according to the second information field), even if the m+1th or subsequent second information field indicates a time domain resource or a valid time domain resource index or a time domain resource index) and/or the m+1th and subsequent second information fields must indicate an invalid time domain resource index or do not indicate a time domain resource or do not indicate a time domain resource index, and/or the mth and subsequent first information fields are ignored by NCT-MT and/or the mth and subsequent first information fields must indicate an invalid beam index or do not indicate a beam or do not indicate a beam index (assuming that the mth second information field corresponds to the mth first information field).

In some embodiments, a second information field that does not indicate a time domain resource or a valid time domain resource index or a time domain resource index and/or is ignored by the NCR may be referred to as an invalid second information field, and a second information field that indicates a time domain resource or a valid time domain resource index or a time domain resource index and/or is not ignored by the NCR may be referred to as a valid second information field.

In some embodiments, if the beam or beam index indicated by the nth first information field (except the first first information field) or the bit value set is the same as the previous first information field (for example, the adjacent previous (n-1) or the first first information field), then the nth first information field and/or the first information field after the nth first information field (the n+1th and thereafter) is ignored by the NCR-MT (that is, the NCR-MT only considers that the first n-1 first information fields indicate a beam or a valid beam index or a beam index, and/or must indicate an invalid beam index or no beam or no beam index or the same beam or beam index or is set to the same bit value (the same as the nth first information field).

))，和/或，必须指示无效的时域资源索引或不指示时域资源或不指示时域资源索引或同样的时域资源或时域资源索引或者设置为同样的比特值(和第m个第二信息域相同)。特别地，该第m个第二信息域也可以称为无效的第二信息域。 In some embodiments, if the time domain resource or time domain resource index indicated by the mth second information field (except the first second information field) or the set bit value is the same as that of a previous second information field (for example, the adjacent previous (m-1) or the first second information field), the mth second information field and/or the second information field after the mth second information field (the m+1th and thereafter) is ignored by the NCR-MT (that is, the NCR-MT only considers that the first m-1 second information fields indicate the time domain resource or the valid time domain resource index or the time domain resource index (described below)

)), and/or, must indicate an invalid time domain resource index or no time domain resource or no time domain resource index or the same time domain resource or time domain resource index or set to the same bit value (the same as the mth second information field). In particular, the mth second information field can also be called an invalid second information field.

In some embodiments, if the first information field in the p-th block indicates an invalid beam index or does not indicate a beam or does not indicate a beam index, and/or the second information field indicates an invalid time domain resource index or does not indicate a time domain resource or does not indicate a time domain resource index or the indicated time domain resource or the time domain resource index or the set bit value is the same as the second information field in a previous block (e.g., the adjacent previous (p-1) or the first block), the NCR ignores the p-th block and/or subsequent (p+1 and subsequent) blocks, and/or the bits in the subsequent blocks are set to specific values (e.g., all '0's). The subsequent blocks may also be referred to as invalid blocks.

In some embodiments, for the case where there are multiple second information domains, different second information domains are based on the same or different time domain resource tables. A new high-level parameter field and/or IE can be introduced in the high-level signaling to configure the time domain resource table for the second information domain (or for the first DCI format). When the time domain resource tables are the same: only one of the time domain resource tables is configured, and all second information domains in the DCI of the first DCI format are based on the time domain resource table. At this time, the bit widths of different second information domains are the same or different. When the time domain resource tables are different: more than one of the time domain resource tables can be configured, and different time domain resource tables correspond to different second information domains. At this time, the bit widths of different second information domains are the same or different. For example, each configuration in the above-mentioned time domain resource table includes one time domain resource or at least one time domain resource, or one or more of the configurations do not include a time domain resource, and other configurations include one time domain resource, which will not be exemplified one by one here. In some cases, whether the second information field is based on the same or different time domain resource tables depends on the number of time domain resource tables or is related to the number of time domain resource tables. When there is only one time domain resource table, they are all based on the one time domain resource table. When there are multiple time domain resource tables, different second information fields can be based on different time domain resource tables. For example, the above-mentioned high-level signaling can be configured with one or more time domain resource tables. If one time domain resource table is configured, the above-mentioned multiple second information fields are all based on the time domain resource table. If the number of configured time domain resource tables is the same as the second information field, the second information field corresponds to the configured time domain resource table one by one, for example, according to the order in which the second information fields are listed in the DCI and the order in which the time domain resource tables are listed in the high-level signaling (the first second information field is based on the first time domain resource table, and so on).

In some embodiments, the correspondence between the first information field (or the beam or beam index or valid beam index indicated by the first information field) and the second information field (or the time domain resource or time domain resource index or valid time domain resource index indicated by the second information field) is determined according to the order in which the first information field is listed in the DCI of the first DCI format, and/or whether the first information field indicates a beam or indicates a valid beam index or indicates a beam index, and/or the order in which the second information field is listed in the DCI of the first DCI format, and/or whether the second information field indicates a time domain resource or indicates a valid time domain resource index or indicates a time domain resource index, and/or the order of the time domain resources indicated by the second information field in the time domain.

For example, the nth first information field in the first DCI format (or the beam or beam index or valid beam index indicated by the nth first information field) corresponds to the nth second information field (or the time domain resource or time domain resource index or valid time domain resource index indicated by the nth second information field). For another example, the first information field in the nth block of the DCI of the first DCI format (or the beam or beam index or valid beam index indicated by the first information field) corresponds to the second information field (or the time domain resource or time domain resource index or valid time domain resource index indicated by the second information field). For another example, the nth first information field indicating a beam or a beam index or a valid beam index (or the beam or beam index or valid beam index indicated by the nth first information field indicating a beam or a beam index or a valid beam index) corresponds to the nth second information field indicating a time domain resource or a time domain resource index or a valid time domain resource index (or the beam or beam index or valid beam index indicated by the nth second information field indicating a time domain resource or a time domain resource index or a valid time domain resource index), and examples are not given one by one here.

In some embodiments, the number of second information fields indicating time domain resources or valid time domain resource indices or time domain resource indices is limited to the number of first information fields indicating beams or valid beam indices or beam indices, or the number of first information fields indicating beams or valid beam indices or beam indices is limited to the number of second information fields indicating time domain resources or valid time domain resource indices or time domain resource indices.

In some embodiments, whether a second information field must indicate a time domain resource or a valid time domain resource index or a time domain resource index is restricted by its corresponding first information field, or whether a first information field must indicate a beam or a valid beam index or a beam index is restricted by the corresponding second information field. For example, if the nth first information field indicates a beam or a valid beam index or a beam index, the nth second information field must indicate a time domain resource or a valid time domain resource index or a time domain resource index, or the nth second information field must indicate a time domain resource or a valid time domain resource index or a time domain resource index, then the nth first information field indicates a beam or a valid beam index or a beam index. For another example, if the first information field in the nth block indicates a beam or a valid beam index or a beam index, then the second information field therein must indicate a time domain resource or a valid time domain resource index or a time domain resource index, or the second information field in the nth block must indicate a time domain resource or a valid time domain resource index or a time domain resource index, then the first information field therein must indicate a beam or a valid beam index or a beam index.

The third information field is described below.

In some embodiments, the downlink control information may include a third information field, and the subcarrier spacing SCS indicated by the third information field is applied to all time domain resources indicated by one or more second information fields. Alternatively, the downlink control information includes multiple third information fields. The second information field and the third information field correspond one to one, and the SCS indicated by different third information fields are applied to the time domain resources indicated by different second information fields.

The following describes how to determine the payload size of the DCI of the first DCI format:

In some embodiments, the payload size of the downlink control information is determined by a bit width of an information field included in the downlink control information and/or is predefined and/or configured by high-layer signaling.

In some embodiments, the payload size of the downlink control information is not less than a predefined minimum value or a value configured by a higher layer signaling and is not greater than a predefined maximum value or a value configured by a higher layer signaling. The predefined minimum value is, for example, 12, and the predefined maximum value is, for example, 140. The maximum value is determined by the bit width (maximum value) of the information field of the downlink control information and/or (the maximum value of) the information field.

For example, when the total number of bits of the information field included in the DCI of the first DCI format is less than the above minimum value (for example, 12), '0's can be appended after the last information field in the DCI of the first DCI format until the payload size is equal to the minimum value.

For example, the payload size N _size of the first DCI format is predefined and/or configured by a high-level parameter. When the total number of bits of the information field included in the DCI of the first DCI format is less than N _size , '0's are appended after the last information field until the payload size is equal to N _size .

In some embodiments, the payload size of the downlink control information in the first DCI format is the same as or different from the payload size of the downlink control information in the second DCI format. The second DCI format is as described above and will not be described again here.

For example, the DCI payload size of the first DCI format must be the same as the payload size of the DCI of the second DCI format. For example, if the payload size of the DCI of the first DCI format is smaller than that of the DCI of the second DCI format, '0's are appended after the last information field of the DCI of the first DCI format until the payload size is the same as that of the DCI of the second DCI format, or bits in the DCI of the second DCI format are truncated/punctured so that the payload size of the DCI of the second DCI format is the same as that of the DCI of the first DCI format. For another example, if the payload size of the DCI of the first DCI format is larger than that of the DCI of the second DCI format, '0's are appended after the last information field of the DCI of the DCI of the second DCI format until the payload size is the same as that of the DCI of the first DCI format, or bits in the DCI of the first DCI format are truncated/punctured so that the payload size of the DCI of the first DCI format is the same as that of the DCI of the second DCI format. The DCI of the first DCI format and the DCI of the second DCI format are monitored at different SSs, and/or, different RNTIs are used (for example, CRC scrambling).

For example, the payload size of the DCI in the first DCI format must be different from the payload size of the DCI in the second DCI format. For example, if the payload size of the DCI in the first DCI format is the same as the payload size of the DCI in the second DCI format, some bits (e.g., 1 '0' bit) are added to the DCI in the first DCI format or the DCI in the second DCI format so that the payload sizes of the two are different. The DCI in the first DCI format and the DCI in the second DCI format are monitored in the same or different SSs, and/or, the same or different RNTIs are used (e.g., for CRC scrambling).

In some embodiments, a PDCCH used to carry a DCI is composed of one or more CCEs (control-channel elements). The aggregation level AL refers to the number of CCEs that constitute a PDCCH. The currently supported AL range is shown in Table 14 below.

Table 14

Aggregation level Number of CCEs 1 1 2 2 4 4 8 8 16 16

In some embodiments, the set of PDCCH candidates that the NCR-MT needs to monitor is defined based on a PDCCH search space set. The search space SS defines the monitoring timing and the search behavior within the monitoring timing (or, defines how/where to search for PDCCH candidates).

In some embodiments, in a cell, the NCR-MT can be configured with multiple SSs. The SS is configured for a portion of the bandwidth BWP (per BWP). However, the index of the SS is for the serving cell (per serving cell). Multiple SSs can be configured in one BWP and serving cell. SS 0 is associated with CORESET 0 by default. For other SSs, the SearchSpace includes high-level parameters for configuring the index of the SS and high-level parameters 5 for configuring the index of the CORESET associated with the SS. Thus, the NCR-MT can know which CORESET each SS is associated with, and the CORSET associated with the search space and the search space configuration in one or more search space sets for monitoring the downlink control information are in the same BWP or different BWPs.

A search space set can be a common search space set (CSS set) or a UE-specific search space set (USS set). Currently, NCR-MT can monitor PDCCH (or monitor DCI) in one or more of the following search space sets, for example:

1) Type0-PDCCH CSS set

Configured by pdcch-ConfigSIB1 in the master information block MIB or searchSpaceSIB1 in PDCCH-ConfigCommon or searchSpaceZero in PDCCH-ConfigCommon. On the primary cell Pcell, it is used to monitor the DCI format 1_0 scrambled by the system information radio network temporary identifier SI-RNTI for cyclic redundancy check CRC, and the PDSCH scheduled by this DCI is used to carry the system information block SIB1.

2) Type0A-PDCCH CSS set

Configured by searchSpaceOtherSystemInformation in PDCCH-ConfigCommon. On Pcell, it is used to monitor DCI format 1_0 whose CRC is scrambled by SI-RNTI, and the PDSCH scheduled by this DCI is used to carry other system information SI.

3) Type 1-PDCCH CSS set

Configured by ra-SearchSpace in PDCCH-ConfigCommon. On Pcell or PScell, used to monitor the DCI format with CRC scrambled by RA-RNTI, TC-RNTI, or MsgB-RNTI.

4) Type2-PDCCH CSS set

Configured by pagingSearchSpace in PDCCH-ConfigCommon. On Pcell, used to monitor DCI format 1_0 with CRC scrambled by P-RNTI.

5) Type3-PDCCH CSS set

Configured by SearchSpace with searchSpaceType=common in PDCCH-Config.

6) USS set

The SearchSpace is configured by searchSpaceType=ue-specific in PDCCH-Config.

In some embodiments, one or more search space sets for monitoring downlink control information of the first DCI format include CSS sets and/or USS sets, and the network device can configure the NCR-MT to monitor the DCI of the first DCI format in the CSS sets and/or USS sets, and the CSS set includes, for example, Type3-PDCCH CSS set. The network device can configure the NCR-MT to monitor the DCI of the first DCI format on the Pcell, PScell, or Scell. For example, if an NCR-MT does not support carrier aggregation/dual connectivity (CA/DC), the network device configures the NCR-MT to monitor the DCI of the first DCI format on the Pcell, that is, the above-mentioned CSS sets and/or USS sets for monitoring the DCI of the first DCI format are on the Pcell. If an NCR-MT supports CA/DC, the network device configures the NCR-MT to monitor DCI of the first DCI format on the Pcell and/or PScell and/or Scell, that is, the CSS sets and/or USS sets for monitoring DCI of the first DCI format are respectively on the Pcell or PScell or Scell. Among them, the CSS sets and/or USS sets for monitoring DCI of the first DCI format may or may not (the network device is configured to be able to or not) be used to monitor DCIs of other DCI formats (for example, DCIs of the legacy DCI format: including DCI formats 1_0, 0_0, 1_1, 0_1, 1_2, 0_2, 2_0, etc.).

In some embodiments, the method may further include: the network device sends search space configuration information to the forwarder, the search space configuration information includes a fourth information field, and the fourth information field is used to configure the forwarder to monitor the downlink control information.

For example, one or more new high-level parameters 6 (or parameters, or fields, corresponding to the fourth information field) are introduced in the search space configuration information SearchSpace IE, and the one or more high-level parameters 6 are used to configure the NCR-MT to monitor the DCI of the first DCI format. The high-level parameters are, for example, dci-Formats-MT-r18, dci-Formats-2_x-r18 (x=8 or 9 or 10), and the one or more high-level parameters 6 are optional (or optional), conditionally optionally present, or conditionally mandatory.

For example, the high-level parameter is conditionally optional, for example, for NCR-MT and/or NCR-MT in FR2 (or FR2-1 and/or FR2-2, and also applicable to other locations) and/or in PDCCH-Config, the parameter is optionally present, that is, it may or may not exist (depending on the network device), otherwise (for example, in PDCCH-ConfigCommon) the parameter does not exist.

For example, the high-level parameter is conditionally mandatory: for example, for NCR-MT and/or FR2, the parameter is mandatory/must exist, otherwise the parameter does not exist or exists optionally.

In some embodiments, the fourth information field may also include information for configuring the aggregation level and/or information for configuring the number of PDCCH candidates, that is, the parameter may also be used to configure the aggregation level (AL) at the same time, that is, to configure the aggregation level of the PDCCH used to carry the DCI of the first DCI format.

Example 1: Assume that this parameter is only used to configure NCR-MT to monitor DCI of the first DCI format and is optional. When this parameter exists in SearchSpace, NCR-MT determines AL/PDCCH candidates based on the parameters (e.g., nrofCandidates) used to configure AL in SearchSpace to monitor DCI of the first DCI format. This parameter can be expressed using ASN.1 as:

Example 2: Assume that this parameter is used to configure the aggregation level (AL) (and the corresponding number of candidates) and is optional. The high-level parameters may include a second high-level parameter for configuring the AL (and the corresponding number of candidates). The second high-level parameter is optional. If a certain aggregation level (or the corresponding parameter) does not exist, the NCR-MT does not search for any candidates with the aggregation level.

When this parameter exists in SearchSpace, the network device only configures one aggregation level and the corresponding number of candidates, or multiple aggregation levels and the corresponding number of candidates can be configured. On the other hand, the network device must configure one aggregation level (and the corresponding number of candidates) (or there must be one parameter for configuring AL (and the corresponding number of candidates) in this parameter), or at least one aggregation level (and the corresponding number of candidates) must be configured (or there must be at least one parameter for configuring AL (and the corresponding number of candidates) in this parameter), or the network device may not configure an aggregation level (and the corresponding number of candidates) (or there may not be a parameter for configuring AL (and the corresponding number of candidates) in this parameter).

In the case where this parameter exists in the SearchSpace and there is no parameter for configuring AL in this parameter, the NCR-MT determines AL/PDCCH candidates based on another parameter for configuring AL in the SearchSpace (e.g., nrofCandidates) to monitor the DCI of the first DCI format. nrofCandidates is conditionally mandatory: when creating a new SearchSpace, nrofCandidates is mandatory. This parameter can be expressed using ASN.1 as:

The one or more fourth information fields may be included in the high-level parameters (eg, searchSpaceType, searchSpaceType-r18) used to configure the search space type in the search space configuration information. The following are two examples:

Example 1: searchSpaceType includes a new high-level parameter 6. searchSpaceType can be expressed using ASN.1 as follows:

Example 2: searchSpaceType-r18 includes a new high-level parameter 6. searchSpaceType-r18 can be expressed using ASN.1 as follows:

A control-resource set (CORESET) is composed of

resource blocks RB and time domain

A CCE consists of 6 resource-element groups (REGs), where one REG is equal to one RB during one OFDM symbol. The REGs in a CORESET are numbered/indexed in ascending order in the time domain, where the number/index of the lowest numbered RB for the first OFDM symbol in the CORESET is 0.

In a cell, NCR-MT can be configured with multiple CORESETs. CORESETs are configured per BWP (that is, the configuration information of a CORESET is included in the configuration information of a BWP, and the resources of the CORESET are in the BWP), but the index of the CORESET is per serving cell (that is, the index of a CORESET is used to uniquely identify the CORESET in a cell). Figure 6 is an example of CORESET configuration, in which, for the same carrier, an NCR-MT is connected to a cell identified by NCGI=5, and a terminal device or another NCR-MT is connected to a cell identified by NCGI=6. The two devices are respectively configured with multiple BWPs and CORESETs in each BWP. The former is configured with 3 BWPs and 4 CORESETs: CORESET 0 is in the initial BWP, CORESET 1 and 2 are in BWP 1, and CORESET 3 is in BWP2. The latter is configured with 2 BWPs and 3 CORESETs: CORESET 0 is in the initial BWP, and CORESET 1 and CORESET 2 are in BWP1.

In some embodiments, each CORESET is associated with only one/one CCE-to-REG mapping. The CCE-to-REG mapping of a CORESET can be non-interleaved or interleaved, described by REG bundles:

Number of symbols

It can be seen that for a PDCCH composed of CCE 0 and CCE 1, the corresponding actual physical resources are different under different CCE-to-REG mappings. Therefore, the network device can perform appropriate configuration according to channel conditions, etc. to ensure the reliability of PDCCH transmission.

The following describes how the network device in 201 sends the DCI in the first DCI format.

Figure 8 is a DCI flow chart of the network device and forwarder transmitting the first DCI format according to an embodiment of the present application. As shown in Figure 8, the sending process includes 1) encoding, and the encoding steps include information element multiplexing, CRC attachment, channel coding, and rate matching; 2) scrambling; 3) modulation; 5) mapping to physical resources; the receiving process includes: 1) demodulation; 2) descrambling; 3) decoding.

The sending process is further described below in conjunction with FIG. 9 .

1) Coding, including:

901, information element multiplexing

The information fields in the DCI of the first DCI format are mapped to information bits (or information bits) a ₀ to a _A-1 in sequence. For example, each information field (including zero-padding bits, if any) is mapped in sequence according to the order in the aforementioned embodiment, the first information field is mapped to the lowest order information bit a ₀ , and then each consecutive field is mapped to a higher order information bit. The most significant bit MSB of each information field is mapped to the lowest order information bit for the information field, for example, the MSB of the first information field is mapped to a ₀ .

902, CRC attachment

Error detection is provided for DCI transmission through a cyclic redundancy check (CRC). The CRC of the DCI of the first DCI format is scrambled using a newly introduced RNTI, which is configured only for the repeater. For example, the newly introduced RNTI may include: network controlled repeater NCR-RNTI (network controlled repeater RNTI), access link indication ACI-RNTI (access link indication/indicator RNTI), access link beam indication ACBI-RNTI (access link beam indication/indicator RNTI), beam indication BI-RNTI (beam indicator/indication/index RNTI), aperiodic beam indication ABI-RNTI (aperiodic beam indication RNTI), side control information SCI-RNTI (side control information RNTI) etc.

The newly introduced RNTI is configured through high-level signaling. For example, a new high-level parameter 7 is introduced, and the high-level parameter 7 is used to configure the RNTI for scrambling the DCI of the first DCI format. The high-level parameter 7 is optional (optional, or optional) or conditionally optionally present (conditionally optionally present) or conditionally mandatory (conditional mandatory). For example, for NCR-MT and/or FR2, the high-level parameter 7 is optional, otherwise, the high-level parameter 7 does not exist. For another example, for NCR-MT and/or FR2, the high-level parameter 7 must exist (mandatory), otherwise, the high-level parameter 7 does not exist.

In some embodiments, a ₀ , a ₁ , a ₂ , a ₃ , ..., a _A-1 denote the bits of the payload (or input bits), and p ₀ , p ₁ , p ₂ , p ₃ , ..., p _L-1 denote the parity bits, where A is the size of the payload, L1 is the number of parity bits, and L = 24. Let the bit sequence a′ ₀ , a′ ₁ , a′ ₂ , a′ ₃ , ..., a _A+L1-1 be:

The generator polynomial (1) is used to calculate the check bit and append the bit sequence as input. The output bits b ₀ , b ₁ , b ₂ , b ₃ , …, b _K-1 are:

Among them, K=A+L1, which represents the number of information bits.

g _CRC24C (D) = [ ^D24 + ^D23 + ^D21 + ^D20 + ^D17 + ^D15 + ^D13 + ^D12 + ^D8 + ^D4 + ^D2 + D+1] for a CRC length of L1 = 24 (1)

In some embodiments, the CRC check bits are scrambled with the bits of the new RNTI, that is, after attachment, the CRC check bits are scrambled by the above RNTI x _rnti,0 , x _rnti,1 , …, x _rnti,15 to form a bit sequence c ₀ , c ₁ , c ₂ , c ₃ , …, c _K-1 , where x _rnti,0 corresponds to the MSB of the RNTI. The relationship between c _k and b _k is:

903, Channel coding

The above bit sequence (or information bit) c ₀ , c ₁ , c ₂ , c ₃ , …, c _K-1 is encoded using Polar coding, and the encoded information bits are represented by d ₀ , d ₁ , d ₂ , d ₃ , …, d _N-1 , where N is the number of encoded information bits.

904, rate matching

The above bit sequence (or information bit) d ₀ , d ₁ , d ₂ , d ₃ , …, d _N-1 is used as input for rate matching. The output bit sequence after rate matching is characterized by f ₀ , f ₁ , f ₂ , f ₃ , …, f _E-1 , where E is the number of information bits after rate matching or the length of the rate matching output sequence. The number of information bits after rate matching is equal to the number of bits (bit number) to be sent on the physical channel (PDCCH), that is, E = M _bit . ,

905, Scramble

Before modulation, the information bits are scrambled.

Assume that the bit block (or bit sequence, or information bit) is b(0),…,b(M _bit -1), where M _bit is the number of bits to be sent on the physical channel (PDCCH). Before modulation, the PDCCH carrying the downlink control information is scrambled using a scrambling sequence, and the scrambling sequence is initialized according to the first parameter and the second parameter, that is, the scrambling sequence c(i) can be used for scrambling according to (2) to obtain a scrambled bit block

Wherein, the scrambling sequence c(i) is a pseudo-random sequence. The scrambling sequence generator is initialized by c _init =(n _RNTI ·2 ¹⁶ +n _ID ) mod 2 ^31. Wherein:

First parameter: for n _ID , when the network device configures scrambling ID information for CORESET, the first parameter is determined according to the scrambling ID information. When the downlink control information is sent in the CSS, the network device does not configure scrambling ID information for CORESET, and the first parameter is determined according to the cell ID.

For example, if DCI of the first DCI format is sent in the USS, if (the associated CORESET) is configured with the higher-layer parameter (scrambling ID) pdcch-DMRS-ScramblingID, n _ID ∈ {0,1,…,65535} is equal to the higher-layer parameter pdcch-DMRS-ScramblingID, otherwise,

(例如(协议规定)(关联的CORESET)不能被配置高层参数pdcch-DMRS-ScramblingID)；或者，如果(关联的CORESET)被配置了高层参数pdcch-DMRS-ScramblingID，n _ID∈{0,1,…,65535}等于高层参数pdcch-DMRS-ScramblingID，否则，

For example, if DCI of the first DCI format is sent in the CSS,

(For example, (protocol provisions) (the associated CORESET) cannot be configured with the higher-level parameter pdcch-DMRS-ScramblingID); or, if (the associated CORESET) is configured with the higher-level parameter pdcch-DMRS-ScramblingID, n _ID ∈ {0,1,…,65535} is equal to the higher-level parameter pdcch-DMRS-ScramblingID, otherwise,

Second parameter: for n _RNTI , when the network device configures scrambling ID information for CORESET, the second parameter is provided by C-RNTI; or, when the downlink control information is sent in the CSS, the network device does not configure scrambling ID information for CORESET, and the second parameter is 0.

For example, if DCI of the first DCI format is sent in the USS, if the higher layer parameter (scrambling ID) pdcch-DMRS-ScramblingID is configured, n _RNTI is provided by the C-RNTI for the PDCCH in the USS, otherwise, n _RNTI =0.

For example, if DCI of the first DCI format is sent in the CSS, n _RNTI = 0 (for example, (protocol specifies) (the associated CORESET) cannot be configured with the higher-level parameter pdcch-DMRS-ScramblingID); or, if the higher-level parameter pdcch-DMRS-ScramblingID is configured, n _RNTI is provided by the C-RNTI for the PDCCH in the USS, otherwise, n _RNTI = 0.

Generic pseudo-random sequences are defined by the length-31 Gold sequence. The output sequence c(n) of length M _PN , n = 0, 1, ..., M _PN -1 (corresponding to the scrambling sequence characterized as c(i) above, M _PN = M _bit ), is defined as:

c(n)=(x ₁ (n+N _c )+x ₂ (n+N _c ))mod 2

x ₁ (n+31)=(x ₁ (n+3)+x ₁ (n))mod 2

x ₂ (n+31)＝(x ₂ (n+3)+x ₂ (n+2)+x ₂ (n+1)+x ₂ (n))mod 2

Wherein, N _c = 1600, the first m-sequence x ₁ (n) is initialized by x ₁ (0) = 1, x ₁ (n) = 0, n = 1, 2, ..., 30. The second m-sequence x ₂ (n) is initialized by c _init .

906, Modulation

通过QPSK 调制，得到complex-valued modulation symbols d(0),…,d(M _symbol-1)，其中M _symbol表示调制符号数。 The above bit block (or bit sequence, or information bit)

Through QPSK modulation, complex-valued modulation symbols d(0),…,d(M _symbol -1) are obtained, where M _symbol represents the number of modulation symbols.

907, mapped to physical resources

The modulation symbols d(0),…,d(M _symbol -1) (optionally, scaled by a factor β _PDCCH ) are sequentially mapped to resource elements (REs) (k,l) _p,μ of the PDCCH DMRS not used for association of the PDDCH to be monitored, in ascending order of frequency domain index k first and then time domain index l. Wherein the antenna port p = 2000, (k,l) _p,μ represents the resource element with frequency domain index k and time domain index l for antenna port p and subcarrier spacing configuration μ (as shown in Table 15 below).

Table 15 Supports transmission of digital

符号数

CCE-to-REG映射为非交织的，且有1个聚合等级AL＝1(即一个PDCCH由1个CCE构成)的PDCCH candidate，由CCE0(包括REGs 0～5)构成，DCI由PDCCH 0承载，PDCCH 0在该PDCCH candidate发送。这种情况下，PDCCH 0对应的调制符号d(0),…,d(M _symbol-1)，

(可选地，由因子β _PDCCH缩放(scaled)后)按先频域后时域(先RE频域索引k升序后时域索引l升序)的顺序映射到CCE0(或者说REGs0～5)中不用于DMRS的RE。 Figure 10 is an example diagram of mapping modulation symbols to physical resources. It is assumed that a CORESET includes RBs.

Number of symbols

The CCE-to-REG mapping is non-interleaved, and there is one PDCCH candidate with aggregation level AL=1 (i.e., one PDCCH consists of one CCE), which consists of CCE0 (including REGs 0 to 5), and the DCI is carried by PDCCH 0, which is sent on this PDCCH candidate. In this case, the modulation symbols corresponding to PDCCH 0 are d(0),…,d(M _symbol -1),

(Optionally, after being scaled by factor β _PDCCH ) mapped to REs not used for DMRS in CCE0 (or REGs0-5) in the order of frequency domain first and time domain second (RE frequency domain index k ascending first and time domain index l ascending).

The following is an explanation of PDCCH DMRS.

In some embodiments, the DMRS reference signal sequence of the PDCCH carrying the downlink control information is initialized according to the aforementioned first parameter.

The UE assumes that the reference signal sequence r _l (m) of OFDM symbol l is defined as:

初始化。其中，l是在时隙中的OFDM符号序号(OFDM symbol number)，

是一个帧中的时隙序号(slot number)，针对N _ID∈{0,1,…,65535}： The definition of the pseudo-random sequence c(i) is introduced below. The pseudo-random sequence generator is composed of

Initialization. Where l is the OFDM symbol number in the time slot.

is the slot number in a frame, for N _ID ∈{0,1,…,65535}:

For example, if DCI of the first DCI format is sent in the USS, if (the associated CORESET) is configured with the higher-layer parameter pdcch-DMRS-ScramblingID, n _ID ∈ {0,1,…,65535} is equal to the higher-layer parameter pdcch-DMRS-ScramblingID, otherwise,

(例如(协议规定)(关联的CORESET)不能被配置高层参数pdcch-DMRS-ScramblingID)；或者，如果(关联的CORESET)被配置了高层参数pdcch-DMRS-ScramblingID，n _ID∈{0,1,…,65535}等于高层参数pdcch-DMRS-ScramblingID，否则，

For example, if DCI of the first DCI format is sent in the CSS,

(For example, (protocol provisions) (the associated CORESET) cannot be configured with the higher-level parameter pdcch-DMRS-ScramblingID); or, if (the associated CORESET) is configured with the higher-level parameter pdcch-DMRS-ScramblingID, n _ID ∈ {0,1,…,65535} is equal to the higher-level parameter pdcch-DMRS-ScramblingID, otherwise,

In some embodiments, when mapped to physical resources, the PDCCH DMRS can be wideband mapped or narrowband mapped.

For example, the reference signal sequence r _l (m) is mapped to REs (k, l) _{p, μ} , where (k, l) _{p, μ} represents a resource element with frequency domain index k and time domain index l for antenna port p and subcarrier spacing configuration μ:

k′＝0,1,2

n＝0,1,…

是RE(k,l) _p,μ对应的复数值(complexed value)。 in,

is the complexed value corresponding to RE(k,l) _p,μ .

If the higher layer parameter precoderGranularity is equal to sameAsREG-bundle, these REs(k,l) _p,μ are in the REGs that make up the PDCCH that the UE will try to decode, that is, narrowband mapping. If precoderGranularity is equal to allContiguousRBs, these REs(k,l) _p,μ are in all REGs of the contiguous resource block set in the CORESET where the UE will try to decode the PDCCH, that is, wideband mapping.

Reference point for k: If the CORESET is configured by the controlResourceSetZero field in the PBCH (or MIB) or PDCCH-ConfigCommon IE, the reference point for k is subcarrier 0 of the lowest numbered RB in the CORESET (that is, k=0 corresponds to subcarrier 0), otherwise, the reference point for k is subcarrier 0 of common RB 0 (that is, k=0 corresponds to subcarrier 0). Where l is the OFDM symbol number in the timeslot. Antenna port p=2000.

According to the above formula, in the REG used to send DMRS, there are 3 REs (RE 1/5/9) in each REG used to map/send DMRS.

FIG. 11A and FIG. 11B are two example diagrams of PDCCH DMRS in the case of broadband mapping and narrowband mapping. In the first example diagram, all RBs in CORESET are continuous (i.e., there is only one continuous RBs set), and in the second example diagram, CORESET includes discontinuous RBs (two continuous RBs sets, respectively). Assume that CCE-to-REG mapping is interleaved, and one PDCCH corresponds to a discontinuous REG. As shown in FIG. 11A and FIG. 11B, in the case of broadband mapping, all REGs in the continuous RBs set in CORESET where PDCCH is located are used to send DMRS, that is, in the continuous RBs set, even if one REG is not used to send PDCCH, it will be used to send DMRS, thereby improving the accuracy of channel estimation. In the case of narrowband mapping, all REGs where PDCCH is located are used to send DMRS, that is, if one REG is not used to send PDCCH, it is not used to send DMRS, thereby saving resources.

Embodiments of the second aspect

An embodiment of the present application provides an information receiving method, which is described from the perspective of a repeater, and the contents that are the same as those in the embodiment of the first aspect will not be repeated.

FIG. 12 is a schematic diagram of an information receiving method according to an embodiment of the present application. As shown in FIG. 12 , the method includes:

1201. A forwarder receives downlink control information sent by a network device, where the downlink control information is in a first DCI format, and includes one or more first information fields for indicating a beam, and/or one or more second information fields for indicating time domain resources, and/or one or more third information fields for indicating a subcarrier spacing.

It is worth noting that the above FIG. 12 is only a schematic illustration of the embodiment of the present application, but the present application is not limited thereto. For example, the execution order between the various operations can be appropriately adjusted, and other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description of the above FIG. 12.

Regarding the first DCI format, the first information field, the second information field, the arrangement of the first information field and the second information field, the corresponding relationship, and the payload of DCI, please refer to the embodiment of the first aspect, which will not be described again here.

The following specifically describes how the forwarder receives the DCI in the first DCI format (how to determine the PDCCH candidate set for monitoring the DCI).

In some embodiments, on an activated serving cell configured with PDCCH monitoring, the NCR-MT monitors a set of PDCCH candidates on one or more CORESETs on an active DL BWP according to corresponding SS sets, wherein monitoring refers to decoding each PDCCH candidate according to DCIs of the monitored DCI format. The downlink control information is carried by a PDCCH candidate in the PDCCH candidate set.

The PDCCH of aggregation level L of the activated DL BWP of the serving cell corresponding to n _CI in the search space set

For any CSS,

其中，Y _p,-1＝n _RNTI≠0，针对CORESET pmod3＝0,A _p＝39827,针对CORESET pmod3＝1,A _p＝39829,针对CORESETpmod3＝2,A _p＝39839,D＝65537。其中，n _RNTI是C-RNTI或上述新引入的RNTI(例如该USS用于发送第一DCI格式的DCI或者说NCR-MT在该USS监听第一DCI格式的DCI时，所述PDCCH候选集合的CCE(起始CCE)索引与新的RNTI相关(相等))。 For USS,

Wherein, Yp _,-1 = _nRNTI ≠0, for CORESETpmod3=0, _Ap =39827, for CORESETpmod3=1, _Ap =39829, for CORESETpmod3=2, _Ap =39839, D=65537. Wherein, _nRNTI is C-RNTI or the newly introduced RNTI (for example, the USS is used to send DCI of the first DCI format or when the NCR-MT monitors the DCI of the first DCI format at the USS, the CCE (starting CCE) index of the PDCCH candidate set is related to (equal to) the new RNTI).

Where N _CCE,p represents the number of CCEs of CORESET p, and these CCEs are numbered from 0 to N _CCE,p -1.

Where n _{CI is} :

For any CSS, _nCI =0.

For USS, except when the serving cell is scheduled from the same serving cell, n _CI = 0. If the NCR-MT is configured with a carrier indication field by CrossCarrierSchedulingConfig, n _CI is the value of the carrier indication field (corresponding to the serving cell).

其中，

Assuming that a CSS is configured to monitor the DCI of the first DCI format, accordingly, according to the above method,

n _CI = 0, the number of CCEs in the CORESET p associated with the CSS is N _CCE,p = 32, and only 2 PDCCH candidates with aggregation level L = 8 are configured for the DCI of the first DCI format. For example, as shown in Figure 13, the NCR-MT monitors the DCI of the first DCI format at PDCCH candidate 0 (composed of CCEs 0 to 7) and PDCCH candidate 1 (composed of CCEs 8 to 15).

In some embodiments, the method may further include: the forwarder sends capability information to the network device, the capability information including or not including fifth information for indicating whether/how the forwarder supports the first DCI format. The fifth information includes one or more of the following information: information for indicating whether the forwarder (hereinafter the forwarder may be replaced by NCR-MT or NCR-Fwd or NCR) supports the first DCI format; information for indicating whether the forwarder supports monitoring DCI of the first DCI format in the CSS; information for indicating whether the forwarder supports monitoring DCI of the first DCI format in the USS; information for indicating whether the forwarder supports dynamic access link beam indication; information for indicating whether the forwarder supports dynamic edge control information.

In some embodiments, the fifth information mentioned above can be defined in the protocol, and the fifth information can be defined as optional or mandatory or conditionally mandatory.

For example, optional means that different forwarders can selectively support the function or feature corresponding to the fifth information, and send the corresponding fifth information when supported, and not send the corresponding fifth information when not supported.

For example, mandatory means that the fifth information is mandatory and/or the function or feature corresponding to the fifth information is mandatory, all forwarders support the function or feature corresponding to the fifth information, and/or all need to send the fifth information.

For example, conditionally mandatory means that the fifth information is mandatory and/or the function or feature corresponding to the fifth information is conditionally mandatory, which means that, under certain circumstances, the forwarder must support the function or feature corresponding to the fifth information and/or must send the fifth information.

For example, if the operating frequency band of the repeater is FR2, the fifth information is mandatory, and if the operating frequency band is FR1, the fifth information may be optional or not mandatory.

For another example, if the operating frequency band of the repeater is in FR2 (or not in FR1) and does not support semi-static access link beam indication/configuration, the fifth information is mandatory, otherwise the fifth information may be optional.

For another example, if the repeater does not support semi-static access link beam indication/configuration, the fifth information is mandatory, otherwise the fifth information may be optional.

In some embodiments, the fifth information may not be defined (correspondingly, the capability information does not include the fifth information). By default, the forwarder supports the DCI in the first DCI format by default, that is, all forwarders support the DCI in the first DCI format, that is, the function or feature of the DCI in the first DCI format is mandatory for the forwarder.

Prior to this, in order to make the configuration sent by the network device to the terminal device UE match the functions supported by NCR-MT, NCR-MT may need to send some capability information related to the functions supported by itself to the network device. All or part of these configuration information and capability information can be sent/interacted via RRC signaling, MAC signaling, or OAM. Based on this information interaction, the network device and NCR-MT perform or do not perform DCI transmission and reception in the first DCI format.
